Glad to hear it's been solved :) Yes, all the MVC templating systems have bits of weirdness that have to be learned the hard way :( Mojolicious is not one I ever used. -- To unsubscribe e-mail to: users+unsubscr...@global.libreoffice.org Problems? https://www.libreoffice.org/get-help/mailing-lists/how-to-unsubscribe/ Posting guidelines + more: https://wiki.documentfoundation.org/Netiquette List archive: https://listarchives.libreoffice.org/global/users/ Privacy Policy: https://www.documentfoundation.org/privacy

I've been banging my head against a wall, because all of mojolicious, perl's IPC and LO are to varying degrees unfamiliar. I certainly mis-understood what I was seeing, processes running LO and with the web network port listening: it's actually correct and harmless. The problem is now resolved, and at the root was related to running the program detached as a daemon. I had a web server running LO internally, which ran correctly from a terminal; ran correctly when detached with magic using () and shell redirects; but which failed when run "properly" with freebsd's 'daemon' command. Obvious in hindsight, the issue was that the daemon, running as user www, didn't have access to a writeable home directory, so LO couldn't run because it needs a rather large file tree there. That was compounded with my misunderstanding of perl's open3() error handling. I'm now using the -env:UserInstallation=XX option to give LO a temporary place to put its bits and bobs, and all - finally - seems to function. At least, LO runs and does the conversions. I do wonder why there's an oosplash process started when I'm using --nologo and --headless though! It also creates more soffice.bin processes than I'd expect, but they seem to tidy themselves away eventually. I'm not sure why I had so much trouble here, compared to a couple of years ago, when I was running LO from apache/php without particular bother. All's well that end's well, I guess. Mojolicious has a steep learning curve, but is much easier and cleaner to use than php for this job. LO works, albeit slowly -- ~20 seconds to do the .odt->.doc conversion on a pi4.

[libreoffice-users] libreoffice grabs network port
Hi all. A bit of a saga for me. I'm using LO headless from within a web server. The server is the perl-based mojolicious, and calls LO do do some file conversions from .odt to .doc and pdf. LO is called like: runcmd( 'soffice', '--headless', '--convert-to', $filter, '--outdir', $outdir, $odtfile ); followed by a call to mojo's render() stuff to pass the file to the user. Which often works. But (with varying frequency) LO seems to grab the web server's port somehow and sets up its own listen on it. This somewhat damages the web link :-| I've seen multiple copies of soffice and oosplash listening on the same port (a high-numbered, obscure one). I can't even see how this is possible The question is, why does it do this, and how do I stop it? TIA.
